Problems solved by technology

[0002] At present, traditional wood coatings, whether oily or water-based, use petrochemical products as raw materials, process and synthesize polymer resins, commonly used are nitro lacquer, amino resin, polyester resin, alkyd resin, phenolic resin, etc. Resin and other major categories, its auxiliary materials diluent, drier, curing agent, etc. also use chemical synthesis raw materials such as formaldehyde, toluene, xylene, ethanol, butyl acetate, acetone, etc., which are harmful to the healthy growth of humans, animals and plants. Certain damage, failed to fully meet the requirements of green environmental protection
In addition, the paint film of traditional paint plays the role of blocking the wood surface from contact with air and moisture, and cannot penetrate into the interior of the wood fiber; due to the coverage of the paint film, the moisture of the wood itself is difficult to dissipate, so it is easy to swell, crack and crack in a humid environment. Alice
Traditional paints have poor weather resistance, such as poor durability for outdoor wooden structures

example 1

[0013] Example 1: Clear wax oil (weight fraction, %)

[0014] Natural vegetable oil derivatives 54

[0015] Carnauba wax 4.2

[0016] Candelilla wax 1.8

[0017] Odorless alkane solvent 38.5

[0018] Pour point depressant 0.5

[0019] Compound drier 1

[0020] Leveling agent, matting agent, etc.

[0021] Put natural vegetable oil derivatives, odorless alkane solvents, etc. into a heated reactor, stir for about 10 minutes, put in carnauba wax and candelilla wax, slowly raise the temperature to 75°C, keep it for about 1 hour until it is completely dissolved. Then put in the pour point depressant, mix well and cool down under rapid stirring conditions, add compound drier and other additives after cooling down to about 30°C, and store or pack after mixing and grinding.

Abstract

The invention relates to a coating combination for pure natural woodenware, which is characterized in that the coating combination is made of natural animal and plant products which are non-toxic, natural and environment-friendly, and capable of sinking into the surface layer of wood and avoiding coating film formation on the surface of the wood when in use, thus enabling the wood to breathe naturally, maintaining the elasticity of the natural wood and preventing the coating combination from cracking, tilting and dropping. The coating combination comprises the following components by weight percent: 30wt% to 70wt% of solvent; 70wt% to 30wt% of natural plant oil derivative; 1wt% to 10wt% of natural wax; 0wt% to 10wt% of pigment; 0wt% to 3wt% of dye and 0wt% to 3wt% of additives, wherein the natural plant oil derivative is particularly one of linseed oil, castor oil, tung oil and soya-bean oil or the product chemically processed from the mixture thereof; and the natural wax is particularly one of carnauba wax, candelilla wax, insect-white wax (Chinese wax) and natural bee wax or the mixture thereof.

Description

Technical field [0001] The present invention relates to the field of wood coatings, in particular to wood coatings for indoor and outdoor use which are modified and compounded from pure natural substances. Background technique [0002] At present, traditional wood coatings, whether oily or water-based, use petrochemical products as raw materials to process and synthesize polymer resins. Commonly used are nitrolacquer, amino resin, polyester resin, alkyd resin, and phenolic resin. Resins and other major categories, its auxiliary material diluent, drier, curing agent, etc. also use formaldehyde, toluene, xylene, ethanol, butyl acetate, acetone and other chemical synthetic raw materials, which are beneficial to the healthy growth of humans, animals and plants. Certain damages, failing to fully meet the requirements of environmental protection. In addition, the lacquer film of traditional paint plays the role of blocking the contact of the wood surface with air and moisture, and can...
